LibreCAD 2.1.0 recently released, is a fully comprehensive 2D CAD drawing tool based on the community edition of QCAD. LibreCAD has been re-structured and ported to Qt version 4 and works cross platform, including Microsoft Windows, Mac OS X and Linux (Debian, Ubuntu, Fedora, Mandriva, Suse). This latest release is a years work and it comes with lots and lots of new features, bugfixes and improvements.

OpenSCAD is a software for creating solid 3D CAD models. It is free software and available for Linux/UNIX, Windows and Mac OS X. Unlike most free software for creating 3D models (such as Blender) it does not focus on the artistic aspects of 3D modelling but instead on the CAD aspects. Most prominent updates to latest release are text(), offset() and list comprehension functionality, as well as a better editor and other GUI improvements.
BRL-CAD is a powerful cross-platform Open Source combinatorial Constructive Solid Geometry (CSG) solid modeling system that includes interactive 3D solid geometry editing, high-performance ray-tracing support for rendering and geometric analysis, network-distributed framebuffer support, image and signal-processing tools, path-tracing and photon mapping support for realistic image synthesis, a system performance analysis benchmark suite, an embedded scripting interface, and libraries for robust high-performance geometric representation and analysis This latest release 7.24.2 includes a plethora of significant bug fixes and improvements to BRL-CAD including fixing ADRT/TIE fast triangle ray tracing on 32-bit platforms, fixing an issue in our FASTGEN converter that affected the import of very complex geometry models, upgrading one of our third-party dependencies (libpng) in response to a vulnerability report, and improving the ‘comb’ and ‘search’ commands with new options for restructuring and searching geometry.
